Pb with BPM => visual check of electrodes + hardware swap
Pb with steerer => Need to identify who will do the intervention and when
Nicolas will ask Kevin for support.
Suggestion: Since the magnetic field stability of the bending magnet which is being used to measure the beam energy is still questioned, it is suggested to wind a wire into a small, flat, electric coil and to place it in the magnet gap or close to it so that the field crosses orthogonally the coil plane, and to monitor the voltage across the coil with an oscilloscope (the e- beam being turned off and the bending magnet being powered, of course). Some dimensional calculation would be needed.
Alignement: Slava got the data from Denis. Alignment is close from nominal values.
The beam quality is good enough to start working with the RF cavity. Even with low power in RF cavity we would like to have a first control of voltage and phase from the control room (Thursday or Friday afternoon).
Some energy instabilities have been observed. Look at correlations (Vincent's measurements) + check that the current operating phase is optimal.
=> Check if position fluctuations are the same with one steerer on, TL/DP/PS.01 off + TL/SST1 and steerer off, TL/DP/PS.01 on + TL/SST2.
Optimum injection trajectory has been recorded on Friday.
Next meeting: 7th Novembre
